' SWITCH-FROG.

Application filed March 26, 1919. Serial No; 285,215.

To all whom it may concern:

Be it known that we, LOUIS HonvATH and THoMAs J. BLACKBURN, citizens ofthe United States of America, and residents of Mingo Junction, county ofJefferson, and State of Ohio, have invented certain new and usefulImprovements in Switch-Frogs, of which the following is a specification.

This invention relates broadly to railway A further object is to providea frog con-..

7 struction whereby the ends of alined rails are secured in permanentlyalined relation.

A still further object is to provide a frog which may be quickly andconveniently applied in position.

With these and other objects in view, the invention resides in thefeatures of construc tion which will hereinafter be fully described,reference being had to the accompanying drawings, in which Figure 1 is atop plan view of the invention;

Fig. 2 is a side elevation of the same; and

Fig. 8 is a section on line 3-3, Fig. 1.

Referring to said drawings, in which like designating charactersdistinguish like parts throughout the several views.

1 indicates a flatbase or bed-plate adapted for mounting upon the usualcrossties in any appropriate manner, suitable recesses or notches 2'forthe reception of attaching spikes being preferably provided at suitablepoints about the outer edge of said base, as shown. Provided in the topface of the base 1 are four sunken seats 3 for the reception of the endsof rails 9, said seats being arranged in two alined pairs with thecenter lines of said pairscrossing each other vat an angle predeterminedto correspond with that of the switch with the main track, or with thatof one cross-over track with the other, as the case may be.

Formed integral with the bed-plate 1 and Specification of LettersPatent.

disposed at one side of and in overhanging relation to each of the seats3 is an angle member 4 the contour of which corresponds substantiallywith that of a common form of angle-bar, or fish plate, and which isdesigned to have a rail end indicated in Fig.

3, a detachable angle-bar 5 being seated upon the opposite side of saidrail and secured in seated relation to said plate by means of spikesdriven into placethrough one or more apertures 6 provided therefor insaid bed-plate. I,

The relatively inclined angle members 4: at one end of the bed-platehave their inner ends meeting integral upright webs 7 which have theirupper edges disposed on a higher plane than said members, or on the sameplane as that of the tread surfaces of rails mounted in place againstsaid members. Said webs are of angular form, one portion 7 a of eachconstituting a tread for the wheels of cars and being disposed in alinedrela tion to the adjacent rails, while the otherportion 7* of eachconstitutes a guard tongue. Said tongues are divergently inclined andeach is located at a spaced distance from the adjacent lateral edge ofan interposed acute-angled frog-point 8, integral with the bed-plate,having its upper face in the same plane as that of the treads of therails which seat upon the bed-plate with their ends in abutting relationto the outer end thereof. Said lateral edges of said frog point aredisposed in direct alinement with the inner edges of the treads 7 of thewebs 7, as shown.

The seats 3 formed in thebed plate have those edges thereof opposite tothe angle members 4; inclined slightly out of parallel relation to saidmembers, as shown in Fi 1, to permit of slight variation of the ang e atwhich the rail end ma to the tread portions of t e webs 7 and of thefrog point 8.

\Vhat is claimed is A one-piece railway frog comprising a bed-platehaving angle-members formed on the top face thereof and adapted toreceive rail ends thereagainst, said members bein arranged in two alinedpairs the projected lines of which cross each other, angular webs formedon said bedplate having portions constituting treads meeting the anglemembers located at one end of said bed. plate, and having other portionsconstitutlie with respect ing divergently inclined guards, a frog pointhaving its outer end meeting the angle members on the opposite endofsaid bed plate and having its point located between and at a spaceddistance from said guards, each lateral edge of said frog point being inalinement With the inner edge of the tread portion of the opposite Web,said bed-plate being plain and flat and having a Width ap- 10proximately its length and also having the LOUIS HORVATH.
